Allow user to kill process during call to keyInYN/keyInYNStrict

[trevorhreed]

I am unable to kill the process (by pressing Ctrl+C or Ctrl+Z) when inside a call to either keyInYN or keyInYNStrict. Regular question calls work as expected, but I would think you would also want to let the user kill the process even in a call to keyInYNStrict. Or perhaps, this could be an option at least?

Hi @trevorhreed, thank you for the report.

If you are using Windows, try Break key (Ctrl+Pause-Break).

Node.js seems to do different behavior about handling SIGINT while TTY in raw mode, in some environments, shells, versions, etc.
It has been discussed at times (e.g. nodejs/node#4758, nodejs/node#3328, nodejs/node#6626).
Someday, Node.js might solve this problem.

Now, better way I think is giving the choice to cancel to user without ^C.
For example, additional keyInYN method (instead of keyInPause) allow user to make the final decision on whether something should do or not, after inputting all information.

That's too bad. I will add a confirmation screen at the end to work around this. Really great library, by the way! Thanks!
